Default Cleaning Brushless Motors

How often should you take apart and clean brushless motors?

Cheers

Per Charlie at novak: Maintenance is low key blow motor out with air or brush out with small brush. DONT use motor spray on the motor take out bearings to clean them. Put rotor immediately in clean plastic bag cause they pick up the smallest stuff.

I just read the article XRC did on doing maintenance to them and on step 3 they tell you to Just like a brushed motor, dirt and grime can build up inside the can of a brushless motor, so clean both the rotating parts and the can itself. Spray the can with motor spray and allow it to dry before reassembly. Wipe down the armature as well.

Also before you put the rotor in the plastic bag, make sure you check the comm as it may need cutting...

its hard to remove the rotor i might damage this thing. what i do is only clean the front bearing exposed thats all.
regarding the rear bearing its imposible to get dirty I only run on roads so i will leave it there.

To be perfectly honest I've to this day never cleaned one. Been running carpet. Be careful putting that rotor back in it will pull it self so hard it can hurt the stater board be sure to line it up right when putting it back in.

I'd say listen to the guys at Novak, if they tell ya not to use motor spray, then don't...after all, they DESIGNED that motor.

Exactly. Next time I see Charlie Suankga, or Steve Weiss I will ask them personally. What better way to find out.

Charlie told us himself in the 4300 thread a while back. I'm gonna stick with compressed air.

You sure do...

Take all the hex head bolts out, front and back. (they're imperial sizes FYI).

Take the front endbell off. - Be sure to save any washer on the shaft and the paper seal.

Wash that front bearing out and re-oil. Take your time.

Take the rear plastic panel off and get the dust out of the recesses.

Few drops on the inner bearing down hurt. Don't go overboard or it will coat all the sensors in gunk.

Take your time and let the oils penetrate. Wipe off the excess and re-assemble.

Older rotors with the kevlar wrap can be difficult to take out. The wrap gets in the way. Just take your time and ease it out. Don't be afraid to use medium pressure though. Just don't yank the rotor out.
